Let A intersection B be 'x'
n(A union B) = n(A) +n(B) - n( A intersection B)
60 =20 + 16 - x
60= 36-x
x = 60 -36
x = 24
n(A union B) = n(A) +n(B) - n( A intersection B)
60 =20 + 16 - x
60= 36-x
x = 60 -36
x = 24

Hi ,
Total students in the sports class ( U ) = 60
Number of students who doesn't like
cricket and soccer = 60 - 12 = 48
i ) 20 + x + 16 = 48
36 + x = 48
x = 48 - 36
x = 12
ii ) Number students who likes cricket
C = 20 + x
= 20 + 12
= 32
iii ) number of students who do not like
soccer = 20
I hope this helps you.
